Good value for money but heavy rolling resistance.
I bought the u3 several weeks ago. The range is great, easily doing 35/40milea. The power and hill climbing are excellent. I easily keep up with my partner on her ADO ultra folding bike and the range is much better. The negatives are that it is much heavier than her bike and you will really struggle carrying it up stairs in railway stations. It’s much bigger when folded than her ADO and much harder to squeeze into a car boot However, the Vitilan is less than half the price of these higher end folders. It is far less sophisticated but does the job well. My major issue is that the rolling resistance due to the 3 inch wide tyres is significant and would be hard work riding without PAS. If a model was released with 2.2 to 2.4 inch wheels this would receive my full 5 stars.
